The short version

  • Only Rank Math has a free tier, so it costs nothing to try first.
  • Each has a real cost: OnCrawl no pricing is published anywhere on the site, so early-stage comparison against Botify or Lumar requires getting quotes from all three before any evaluation can start.; Rank Math all paid tiers are annual-only with no monthly option, so evaluating Pro or Business month to month before committing is not possible.
  • They diverge on capability: OnCrawl covers Log file analysis, Rank Math covers Free schema generator.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

OnCrawl

  • A large publisher or marketplace diagnosing wasted crawl budget on parameterised or low-value URLsnot Rank Math
  • A technical SEO team that needs server log data joined to crawl data, not just a crawl report on its ownnot Rank Math
  • An enterprise site comparing crawl-plus-log platforms against Botify or Lumar before committing to a multi-year contractnot Rank Math
  • A team wanting custom segmentation of crawl and log data without writing SQL against a raw exportnot Rank Math

Rank Math

  • A WordPress site owner who wants more schema types and keyword optimisation than Yoast's free tier provides, at no costnot OnCrawl
  • An agency managing dozens of client WordPress sites that wants a per-site-count licence rather than per-site billingnot OnCrawl
  • A team that wants rank tracking built into the WordPress dashboard rather than as a separate subscriptionnot OnCrawl
  • A site migrating away from a paid competitor and wanting a free tier competitive enough to not need Pro immediatelynot OnCrawl

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

OnCrawl

  • No pricing is published anywhere on the site, so early-stage comparison against Botify or Lumar requires getting quotes from all three before any evaluation can start.
  • Log file analysis requires the customer to actually supply raw server logs, which many marketing teams cannot get from their infrastructure team without a separate internal project.
  • It is a smaller company than Botify, so enterprise buyers evaluating vendor stability and roadmap longevity weigh that against the lower likely price.
  • The interface and terminology assume a working knowledge of crawl budget and log analysis concepts, so it is a poor fit for a generalist marketer without technical SEO background.
  • Data retention periods are tied to plan tier, so historical trend analysis beyond the contracted retention window is not available without upgrading before the data would otherwise be purged.

Rank Math

  • All paid tiers are annual-only with no monthly option, so evaluating Pro or Business month to month before committing is not possible.
  • The advertised price is a first-year introductory rate; renewal pricing is roughly 10 to 18 percent higher across every tier, which is easy to miss when comparing sticker prices to Yoast.
  • Switching an established WordPress site to or from Rank Math risks losing accumulated redirect rules and schema configuration if the migration is not done carefully, which discourages later switching regardless of price changes.
  • It is WordPress-only, so any team running a non-WordPress CMS gets nothing from this product at all.
  • The generous free tier depends on upselling Pro and Content AI trials inside the plugin dashboard, which some users find intrusive compared to Yoast's comparatively quieter free experience.

Answered from the vendors’ own pages

OnCrawl: Do I need to provide my own server logs?

Yes, log file analysis is only available if you can export raw access logs from your web server or CDN; without them OnCrawl functions as a crawler only.

Rank Math: Is Rank Math really free?

Yes, for unlimited personal websites, with 18 schema types and unlimited keyword optimisation at no cost; client sites and rank tracking require a paid tier.

OnCrawl: How much does OnCrawl cost?

It is not published. Pricing is quoted based on crawl volume, log volume and retention period; get a quote before comparing it to Botify or Lumar.

Rank Math: Can I pay monthly instead of annually?

No. All paid plans are billed annually only; there is no monthly billing option.

OnCrawl: Is this suitable for a small business site?

Generally not economically; the log analysis capability that justifies the cost only pays off once a site is large enough that Google is not crawling every page anyway.

Rank Math: Does the advertised price stay the same at renewal?

No. Every paid tier renews at a higher rate than the first-year introductory price, by roughly 10 to 18 percent depending on the plan.
